SIGN.

Specificaton of Letters Patent.

Patented June 7, 1910.

Application filed December 8, 1909. Serial No. 531368.

To all whom 'it may concem:

Be it known that I, PAUL KAMM, a citi-.

zen of the United States, residing at Chicago, county of Cook, andState' of Illnos, have invent'cd certain new anduseful I mprovements inSigns, of which the following is a spccificaton. i

My invention relates to improvements n si ns and has for its objecttheproduction Q an illuminated sign of improved construction andoperation.

The invcntion conssts in the combination and arrangemcnt of partshereinafter de- The prcferred form of Construction as' llustrated n thedrawings comprises a suitable box or casing l having a hinged top 2provided with a downwardly curved reflector 3 at its outer or openingend. One side of box l is closed by a transparent glass plate 4 behindwhich is removably mounted a frame E carrying a Wire casing or otherforaminated sign member G. A signis prepared on the sign member 6 bypainting or otherwise color-ing the same, care eing taken that theinterstices or perforations therein shall not be closed by the' paint orother coloring matter. Behind sign member 6 is removably mounted a'frame 8 carrying a transverse sign plate 9 preferablybf glass. Asign isformed on the plate 9 by blocking the same out thereon with paint orother o aquematter so that the desired sign shall e-re resented by theportions of said glas plate eft transparent.

On the exterior of the casing electric light bulbs 7 are mountedimmediately above plate 4 and in 'such position that the reflector 3,when the top 2 s closed, will throw the rays of light thereon upon theforam inated sign member 6. Within the casing l and on the side thereofopposite to the foraminated sign member 6 are arranged anotherset ofelectric light bulbs 10,. adapted to illuminate the interier of casn 1.Lights 7 and 10 are connected in suitable electric circuits and suitablemeans (not shown) are pro vided for alternately lighting or flashingsaid exterior and interier lights as will be readily understand by thoseskilled inthe art. YVhen lights 7 are lighted the sign matter on member6 will be rendered visible thereby. When lights 7 are extinguished andlights 10 lighted the sign matter on member 6 will not be visible andthat on plate 9 will appear owing to the passage of light therethrough.The light passing through plate 9 must also pass through member 6` andfor this reason care should be taken that. the interstices on member 6are not closed.

In Figs. 3 and 4 I have illustrated a modi fied form of Construction inwhich o posite sides of the casing 1' are provide with sign' members 6and 9 as above described. In this case eXterior lights 7 are mounted onthe opposite sides ofcasing "1 immediately above lates 4 and reflectors3' and 3" provided or the same. The interier lights 10' are, in this,instance, placed upon a side of the box 'located between the oppositelydisposed sign members 6. Otherwise the construction is exactly the sameas in the -case above described and the operation is the same exceptthat both signs will .be Visible in two directions instead of one.

While Ihave shown what I deem to be the preferablerform of my inventionI do not wish to be limited thereto as there might be various changesmade in the details of Construction and arrangement of pa'rts describedwithout departing from -my invention. I, therefore, do not wish to belimited to the exact details of construction set forth, but desire toavail myself of such variations and inodifications ascome within thescope of the appended claim.

Having described my invention what I' claim as new and desire to secureby Leti ters Patenta is:

An illumnatedsi comprising a casin a foraminated mem er in one'sde of'sad 105 site to said foramnated member; lights on 7110' the exte-io' ofsaid casig above said fo- In testiiony-whereof I have signed my ramnatemember; amuwardly swngiig name to this specificatio' in the presence oftop for said casi'g; a re ector on said top two subscribmg witnesses.
